10553 Hard Wall Picture Hooks Large 100 pack
The smooth face of a wall often hides bricks, blocks or concrete. These usually do not take kindly to the long pins used in traditional picture hooks.
These picture hooks for hard walls are moulded in high-grade polymer. They have hardened short steel pins pre-loaded. Use a small hammer to drive them into the wall surface. They are designed for use where the plaster is very thin, so that most of the pin length goes into the wall material. Wall surfaces vary, so always check before hanging a picture.
Use cord or braided wire on the picture. Do not use these hooks for heavy or valuable pictures or where items underneath might get damaged.
There are three sizes of hard wall hooks in the range, each with very sharp hardened steel pins:
10553 Large, 41mm, with four 1.37mm x 14mm pins and a hole for a picture pin
The hole is designed to take a normal 25mm approx hardened picture pin. This can help secure the hook on some softer wall surfaces.
